Abstract
Automated inspection of manufactured parts is a challenging problem and a crucial issue for any production process. When concerned with dimensional tolerancing, CAD models are a highly desirable reference, as they describe precisely the parts under inspection. However, the time needed to identify the right model in a large CAD database is far too long for on-line inspection because of the huge amount of data to be analyzed. In this paper, we propose to use a vision-based representation for the parts which is much less accurate than CAD descriptions, but offers very low storage requirements, thus speeding up the identification stage. We discuss the inspection system proposed and report our preliminary results in converting CAD models to their simplified representation.
